I think that Ben Gordon would be a great free agent signing if the Blazers could go out and get him. The Blazers need a 3rd scorer to help out Lamarcus and Brandon so why not. Think about it they cant get a scoring center because that would take playing time from Oden and Przybilla. They shouldnt get a small forward because they have Batum, Outlaw and Webster coming back. There weak position is point guard. Blake can hit the 3 and knows the offense but is a weak scorer and Sergio should probably been gone this summer due to his overall lack of skill and the emergence of Jerryd Bayless. I know Gordon isnt a point guard but he really just needs to get the ball over half court and let Roy run the first team offense. He is a great shooter and would definetly open things inside for the big men.
The Team would look like this:
PG: Gordon,Blake,Bayless SG: Roy,Rudy,Webster
SF:Batum,Outlaw PF: Lamarcus,Frye
Thats a pretty good team right there
